I guess we are drifting off. I was just considering some alternatives to 
"final(false)" which doesn't work.

The attributes sometimes need to be selected conditionally, e.g. when 
building a library for static or dynamic linkage (at least on windows 
where not everything is exported by default). Right now, you don't have 
an alternative to code duplication or heavy use of string mixins.
